Water-cooled unit commonly known as freezer, chiller, ice water machine, freezing water machine, cooling machine, etc., because of the wide use of all walks of life, so the name is countless.The principle of its properties is a multifunctional machine that removes liquid vapors through a compression or heat absorption refrigeration cycle.The steam compression chiller consists of four main components of the steam compression refrigeration cycle compressor, evaporator, condenser, and part of the metering device in the form of a different refrigerant.Absorption chiller uses water as a refrigerant, and relies on the water and lithium bromide solution between, in order to achieve a strong refrigeration effect of affinity.

Water-cooled unit are commonly used in air conditioning units and industrial cooling.In air conditioning systems, chilled water is usually distributed to heat exchangers or coils in air handling units or other types of terminal equipment for cooling in their respective Spaces, and then the cooling water is redistributed back to the cooling that has been cooled off.In industrial applications, chilled water or other liquids are cooled by pumps through processes or laboratory equipment.Industrial chiller is used to control product, mechanism and plant machinery cooling in all walks of life.
